Prolonged Implantation of Sinus Devices and Implications for Chronic Rhinosinusitis: A Case Report and Review of the Literature.

Background: Implantation of sinus stents and spacers can be used as adjuvant management to maintain patency of sinuses after endoscopic sinus surgery for chronic rhinosinusitis. These implants are typically removed several weeks after surgery. We present two cases of different patients who were initially treated by different physicians and were found to have retained sinus spacers in their paranasal sinuses 6-10 years after implantation.

Quantification of Aerosol Concentrations During Endonasal Instrumentation in the Clinic Setting.

Objective: Recent anecdotal reports and cadaveric simulations have described aerosol generation during endonasal instrumentation, highlighting a possible risk for transmission of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) during endoscopic endonasal instrumentation. This study aims to provide a greater understanding of particle generation and exposure risk during endoscopic endonasal instrumentation.

Study Design: Prospective quantification of aerosol generation during office-based nasal endoscopy procedures.

Quantification of Aerosol Particle Concentrations During Endoscopic Sinonasal Surgery in the Operating Room.

Background: Recent indirect evidence of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) transmission during endoscopic endonasal procedures has highlighted the dearth of knowledge surrounding aerosol generation with these procedures. As we adapt to function in the era of Coronavirus Disease 2019 (COVID-19) a better understanding of how surgical techniques generate potentially infectious aerosolized particles will enhance the safety of operating room (OR) staff and learners.

Objective: To provide greater understanding of possible SARS-CoV-2 exposure risk during endonasal surgeries by quantifying increases in airborne particle concentrations during endoscopic sinonasal surgery.

A Comparison of Sphenoid Sinus Osteoneogenesis in Aspirin-Exacerbated Respiratory Disease.

Background: Aspirin-exacerbated respiratory disease (AERD) is characterized by excessive leukotriene production, diffuse polyp burden and osteitic bone changes. These bony changes have not been previously characterized.

Objective: The aim of this radiographic study is to characterize the bony changes noted on computed tomography (CT) scans of the sphenoid sinus in patients with AERD compared to other diseased sinonasal inflammatory states and non-diseased controls.

Understood? Evaluating the readability and understandability of intranasal corticosteroid delivery instructions.

Background: Allergic rhinitis is a widespread disease that has significant quality-of-life ramifications. Symptoms include rhinorrhea, nasal obstruction, cough, and postnasal drip. Intranasal corticosteroids are a hallmark of treatment of allergic rhinitis.
